本篇論文旨在探討適用於物聯網應用的低電壓、低功率之升壓型直流—直流轉換器。本文提出兩種不同的控制方法，以屏除傳統轉換器對補償器的需求，並抑制輸出電壓漣波。另針對此升壓型直流—直流轉換器在不同應用環境提出三種啟動機制，分別達成低電壓啟動（155毫伏）、簡化啟動機制及屏除一次性輔助啟動電路需求。最後，以直流—直流轉換器為基礎，設計一具儲能及調節功能之新型轉換器架構（單電感雙供給電源轉換器），其主要是為解決物聯網相關產品之電源供給問題。上述控制方法、啟動機制及轉換器架構分別實現於四個獨立晶片，且四晶片均使用台灣積體電路公司 180 奈米製程製作。

This dissertation mainly focuses on the design of low voltage/power boost dc–dc converter for internet-of-things (IoT) applications. This dissertation proposes two control methods to suppress the output voltage ripple. Both of them can be implemented without any compensator. Moreover, this dissertation proposes three different startup strategies for different applications. One of them can successfully startup with a 155-mV input voltage, while the other two simplify the startup procedure and eliminate the circuits that are only activated at startup. Finally, this dissertation proposes a novel topology, which features storing the energy and conditioning the output voltage, i.e., Single-Inductor Dual-Supply (SIDS) converter. The SIDS converter is designed for the power management of IoT applications. In fact, “one topology”, “two control methods”, and “three startup strategies”, are implemented in four independent chips. All the chips were fabricated by using the TSMC 0.18-μm 1P6M mixed-signal process.
